Definitions

  • the invention relates to improvements in paper machines, and more particularly to an improved pressing arrangement for dewatering a web received from a forming section of a papermaking machine.
  • a further object of the invention is to provide an improved paper machine press which utilizes the improved effects of an extended nip press and utilizes a combination of a conventional two roll press with an extended nip press.
  • a still further object of the present invention is to provide an improvement in papermaking machines for providing an improved quality web and reducing energy requirements of a papermaking machine by an improved press section.
  • FIGURE of the drawing is a somewhat schematic front elevational view of a paper machine press section embodying the principles of the present invention.
  • a formed paper web travels from a forming section through the illustrated press section.
  • the web is designated by W and is transferred to various supporting elements in different positions through the machine as indicated by the numerals W-1 through W-8.
  • the web is formed on a forming wire which may be a Fourdrinier wire or the lower wire of a twin wire machine, and the wire is designated at 10 passing down over a couch roll 11 and a turning roll 12 in a descending pick-off run. This position of the web prior to being picked off the wire is designated at W-1.
  • a forming wire which may be a Fourdrinier wire or the lower wire of a twin wire machine
  • the web is then transferred to an upper first press felt 13 which passes downwardly into close running relationship with the wire 10 and picks the web off the wire because of a suction pick-up roll 14.
  • the web in being picked off the wire follows the felt 13 into position W-2.
  • a lower felt 16 is guided up into close running relation with the upper felt 13 passing over a guide roll 17 so that the web W-2 becomes sandwiched therebetween passing into position W-3.
  • Both felts 13 and 16 with the web sandwiched therebetween pass into a first nip N-1.
  • the nip N-1 is formed between an upper roll 20 and a lower roll 21.
  • both rolls are open rolls and are pressed together with a nip pressure in the range of 400 to 800 pli.
  • the felts are separated with the upper felt 13 passing over the guide roll 15, and the lower felt 16 traveling onto guide roll 18.
  • Web transfer to the lower felt 16 is effected by a suction shoe 19, and the web follows the lower felt into the position shown at W-4 as the felts separate.
  • the relatively wet web is pressed for initial water removal with the water passing into the felts and into the grooves of the rolls 20 and 21.
  • the felts in their total run pass over guide rolls, felt dryers and cleaners and felt stretch rolls in a manner which will be well known to those versed in the art, and the additional felt guide and felt treatment rolls are not numbered.
  • the double felts 22 and 25 with the web sandwiched therebetween pass into the nip N-2 which is formed between an upper press roll 30 which may be an open roll, and a press shoe 31.
  • the press shoe 31 is supported on a pivot pin 32 and has a concave upper surface to form an extended press nip.
  • the leading edge 33 of the shoe is relieved so that when a lubricating liquid is supplied thereto by lubricating supply means 38, a hydraulic layer of pressing liquid builds up between the upper surface of the shoe and a looped impervious belt 39.
  • the belt 39 passes through the nip with the felts.
  • the shoe is pressed upwardly being supported on a piston 34 in a cylinder 35 with liquid pressure being supplied beneath the piston by suitable pressurizing means.
  • the shoe is pressed upwardly by a force to give a larger pressing pressure in the nip N-2 than in the first nip N-1, and preferably a pressure in the range of 4000 to 8000 pli is applied.
  • the looped impervious belt 39 is guided on an annular shoe arrangement which is slightly less than the diameter of the belt 39 so that the belt is guided and slides freely over the annular guide arrangement 28.
  • the web is transferred to the upper felt 22 by a suction shoe 29 within the upper felt.
  • the web then is in the location W-7.
  • the lower felt 25 is guided away from the upper felt by a guide roll 27.
  • the upper and lower felts 22 and 25 pass over suitable felt cleaning and drying means and felt guide rolls and stretch rolls in a manner which will be well known to those versed in the art so that the elements need not be described in detail and they are not numbered on the drawing.
  • the web is transferred to a fifth felt 36 which passes over a suction roll 37 for the transfer.
  • the web is then in the position W-8 to pass downstream to dryer drums.
  • the web is picked off the forming wire 10 and passes sandwiched the between upper and lower first felts 13 and 16 into the first nip N-1 formed between the upper and lower press rolls 20 and 21.
  • the web On the offrunning side of the nip N-1, the web is transferred to the lower felt by the suction shoe 19 and then transferred to the third felt by the suction roll 23.
  • the web is carried in the position W-6 sandwiched between the second set of felts 22 and 25 into an extended nip press.
  • the extended nip press is formed between the upper roll 30 and the lower press shoe 31.
  • the web is transferred to the upper felt by a suction shoe 29, and from position W-7 is transferred onto the fifth felt 36 by the suction roll 37 into position W-8.
  • I have provided a new and unique pressing arrangement wherein the web is first dewatered in a regular two roll press to remove a large amount of water from the wet web into the two carrying felts. Thereafter, the web is passed into an extended nip press where pressure is applied for an extended time with the bulk of the first excess water having been removed in the first press and the complete pressing operation is finished in the second extended nip.
  • the second press is also a double felted press with the water being removed in both directions and with both nips being double felted presses, the press arrangement is particularly well suited to use in forming one sided paper which may be formed by a twin wire former. Essentially dewatering is accomplished at a substantial rate in both directions in each of the press nips.
